Lewis structure
Draw the Lewis structure of nitrogen. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the nitrogen (n_N, val = 5) atoms: 2 n_N, val = 10 Calculate the number of electrons needed to completely fill the valence shells for nitrogen (n_N, full = 8): 2 n_N, full = 16 Subtracting these two numbers shows that 16 - 10 = 6 bonding electrons are needed. Each bond has two electrons, so in addition to the 1 bond already present in the diagram add 2 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 2 bonds by pairing electrons between adjacent highlighted atoms: Answer: | |
